Bringing European parallel programming technology to the exascale era
  • EPEEC will develop and deploy an integrated ecosystem of programming environment components that will enable highly productive exascale programming
  • Funded by the European Commission, the project started on 1 October 2018

Barcelona, 20 November 2018. Launched on 1 October 2018, the European EPEEC project (European joint Effort toward a Highly Productive Programming Environment for Heterogeneous Exascale Computing) has received €3.9 M in funding to develop and deploy a production-ready parallel programming environment. This will turn future exascale supercomputers, which will be overwhelmingly heterogeneous, into manageable platforms for application developers in different domains.

The high-performance computing (HPC) community is working diligently towards building, supporting and using exascale supercomputers. However, while considerable progress has been made in systems software – including programming models and runtime systems – in providing more transparent support for large-scale deployments, there is a long way to go in terms of providing highly efficient, generic and portable support. In particular, there is no available integrated ecosystem of programming environment components targeting highly productive exascale programming that can exploit the full power of emerging hardware.

groupThis is where EPEEC comes in. The project consortium will significantly advance and integrate existing state-of-the-art components based on European technology (programming models, runtime systems, and tools) with key features enabling three overarching objectives: high coding productivity, high performance, and energy awareness.

“Given the imminent arrival of exascale supercomputers, we have very high expectations for the outcomes of this project. Using a supercomputer efficiently should not be limited to ‘ninja programmers’; it should be open to domain application developers with a general understanding of parallel progamming,” said EPEEC’s technical manager Antonio J. Peña, leader of the Accelerators and Communications for HPC at Barcelona Supercomputing Center (BSC). “The advances made in EPEEC will directly benefit society by speeding up  the development of large-scale simulators leading to the discovery of new drugs or more accurate weather forecasts, for example,” he added.

Five applications representing different scientific domains will be used as part of a strong interdisciplinary co-design approach and as technology demonstrators: AVBP (fluid dynamics and combustion), DIOGENeS (nanophotonics / nanoplasmonics), OSIRIS (plasma physics), Quantum ESPRESSO (materials sciences) and SMURFF (life sciences). EPEEC will exploit results from past Future and Emerging Technologies (FET) projects that have led to the cutting-edge software components it builds upon, and aims to influence the most important parallel programming standardisation bodies.

The project will ensure the composability and interoperability of its programming models and runtimes, which will incorporate specific features to handle data-intensive and extreme-data applications. Enhanced leading-edge performance tools will offer integral profiling, performance prediction, and visualisation of traces.

An automatic generator of compiler directives will provide outstanding coding productivity from the very beginning of the application developing/porting process. Developers will be able to leverage either shared memory or distributed-shared memory programming flavours, and code in their preferred language (C, Fortran, or C++) and accelerator programming model (OpenMP, OpenACC, CUDA, or OpenCL).
